In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

According to one embodiment of the present invention there is provided an automatic webbing retraction device adapted to snap onto a fixed member, such as a bedside bed. As shown in fig. 1 to 11, the automatic webbing retractor 10 includes: a base 101 including a bottom surface 1011 and a sidewall 1012 enclosing a housing, the bottom surface 1011 having a protrusion 1013 at the center thereof, the sidewall 1012 having a slot 1014; a reel 102 having a through hole 1021 at a center thereof corresponding to the protrusion 1013, the reel 102 being mounted within the housing on the bottom surface 1011, the through hole 1021 surrounding the protrusion 1013; a coil spring 103 fitted around the projection 1013 and on the reel 102, and one end of the coil spring 103 is fixed to the projection 1013 and the other end is fixed to the reel 102; and a webbing 104 wound in a ring shape, a fixed end of which is fixed to the reel 102, and a free end 1042 of which passes through the slit 1014 of the side wall; wherein, when the free end 1042 of the webbing belt 104 is pulled outward by an external force, the reel 102 rotates in a forward direction, so that the coil spring 103 is wound tightly; when the external force is removed, the reel 102 rotates in the reverse direction under the tension of the coil spring 103, thereby winding the webbing 104 onto the reel. In some embodiments, the forward direction may be clockwise and the reverse direction may be counterclockwise, or vice versa.

The automatic webbing take-up device 10 may further include a spool cover 105 centrally provided with a through hole aligned with the protrusion 1013 of the base 101, mounted on the spool 102, covering the webbing 104, the coil spring 103 and the spool 102. The webbing automatic retraction device 10 may further include a base cover 106, the base cover 106 being secured to the base 101 and overlying the housing of the base 101. As shown in fig. 1, 10 and 11, the base cover 106 has a hole in the center. Optionally, the center of the protrusion 1013 of the base 101 is also provided with a central through hole. The hole in the center of the base cover 106 is aligned with the central through hole of the projection 1013 of the base 101 and may be bolted by screws to secure the two together. When the base 101 is integrally formed on the side panel 201 of the bedside table 20, the central through hole of the projection 1013 of the base 101 is directly provided on the side panel 201. The base cover 106 may be secured to the side panels 201 by screw bolting to cover the base 101 and other components inside. In some embodiments, a flexible material may be used for the base cover 106, for example made of or wrapped with a flexible material to prevent injury to the infant from impact within the bed.

In the present embodiment, the base 101 is integrally formed on the side panel 201 of the bedside table 20, i.e., the bottom surface 1011 of the base 101 is integrally formed with the side panel 201, and the side wall 1012 is also integrally formed with the two. Alternatively, however, the base 101 may be a separate component that is not integrally formed with the side panel 201, and the bottom surface 1011 and the side wall 1012 may not be integrally formed and may be connected together in a manner known in the art.

In some embodiments, as shown in fig. 12 and 13, the automatic webbing retractor 10 may further include an engagement member 107, wherein the engagement member 107 is disposed at a free end 1042 of the webbing 104. The catch 107 includes a first catch 1071 and a second catch 1072 that secure the free end 1042 of the webbing 104 to a large bed (not shown) near the bed side 20 by a snap action. The engagement member 107 may be of other forms commonly used in the art so long as it is capable of securing the webbing 104 to a large bed.

Referring to fig. 2, 3, and 6, the bottom surface 1011 of base 101 includes an annular projection 10111 disposed about projection 1013. The reel 102 includes flanges 1022 disposed around the through hole 1021, the flanges 1022 being formed on both sides of the reel 102. Annular projection 10111 corresponds to flange 1022 of reel 102 such that flange 1022 is received in the annular region formed by annular projection 10111 and projection 1013. In this way, by having the flange 1022 of the spool 102 received in the annular projection 10111 and the projection 1013 forming an annular region, the position of the spool 102 can be restricted so that it is more smooth during rotation.

As shown in fig. 3, the spool 102 further includes a plurality of projecting ribs 1023 extending from the flange 1022, the projecting ribs 1023 having the same height as the flange 1022 with respect to the plane of the main body of the spool 102, i.e., the projecting ribs 1023 are in the same plane as the flange 1022. Alternatively, the projecting ribs 1023 are symmetrically arranged, and in the present embodiment, 8 projecting ribs 1023 are provided, which are symmetrically arranged. By providing the projecting rib 1023, the area of contact between the coil spring 103 and the reel 102 with each other is reduced and the frictional force therebetween is reduced when the coil spring 103 is mounted on the reel 102.

As shown in FIG. 2, bottom surface 1011 of base 101 further comprises a plurality of projecting ribs 10112 extending from annular projection 10111, and projecting ribs 10112 are the same height as annular projection 10111 with respect to bottom surface 1011, i.e., annular projection 10111 and projecting ribs 10112 are in the same plane. Alternatively, the projecting ribs 10112 are symmetrically arranged, and in the present embodiment, 8 projecting ribs 10112 are provided, which are symmetrically arranged. By providing the projecting ribs 10112, the contact area of the reel 102 and the base 101 with each other is reduced and the friction force therebetween is reduced when the reel 102 is mounted on the base 101. The side wall of the projection 1013 of the base 101 is provided with a cutout 10131, and the cutout 10131 is used for catching one end of the coil spring 103. As shown in fig. 8 and 9, the cross section of the cut 10131 is Y-shaped, so that the coil spring 103 can be clamped in two directions, and one end of the coil spring 103 can be clamped on the left side of the Y-shaped cut 10131 and the right side of the cut 10131. Shown in fig. 9 is the coil spring 103 snapped to the right of the Y-shaped cutout 10131 so that when an external force pulls the webbing 104, the coil spring 103 will be wound up in the counterclockwise direction and when the external force is removed, the webbing 104 will be tightened in the clockwise direction under the tension of the coil spring 103. On the contrary, if the coil spring 103 is stuck at the left side of the Y-shaped cutout 10131, it can be realized that the coil spring 103 will be wound up in the clockwise direction when the webbing 104 is pulled by the external force, and the webbing 104 will be wound up in the counterclockwise direction by the tension of the coil spring 103 when the external force is removed.

As shown in FIG. 3, the reel 102 further includes two semi-annular protrusions 1024 disposed opposite one another on one side thereof, and a lug 1025 located between opposite ends of the two semi-annular protrusions 1024. A semi-annular projection 1024 surrounds the flange 1022 and is located peripherally to the flange 1022. One end of the half-ring projection 1024 is narrowed, and a gap 1026 is formed between the narrowed ends of the two half-ring projections 1024. The space 1026 is used to catch one end of the coil spring 103. The lugs 1025 are used to secure the secured end 1041 of the webbing 104. One end of the semi-annular projection 1024 is narrowed to prevent the tip of the coil spring 103 caught in the gap 1026 from being hooked to the webbing 104. As shown in fig. 6, 8-9, the webbing 104 is looped around the semi-annular projection 1024, the fixed end 1041 of the webbing 104 is secured to the lug 1025, and the free end 1042 of the webbing 104 extends out of the slot 1014 in the side wall 1012.

As shown in fig. 4, which shows an embodiment of the coil spring 103, both ends of the coil spring 103 are respectively rolled up for being caught in the cutout 10131 of the base 101 and the space 1026 of the reel 102, so that one end thereof is fixed to the base 101 and the other end thereof can be wound up with the rotation of the reel 102 according to an applied external force or moved in the opposite direction by the tension of the coil spring 103 when the external force is removed.

According to the automatic webbing winding device 10 provided by the invention, one end of the coil spring 103 is clamped in the notch 10131 of the base 101, and the other end of the coil spring 103 is clamped in the gap 1026 of the reel 102, so that when no external force is applied to pull the webbing 104 outwards, the webbing 104 is always in an automatic winding state under the action of the coil spring 103. When the webbing 104 is to be used, pulling the webbing 104 outward causes the spool 102 to rotate in the forward direction, thereby winding the coil spring 103, and achieving a force that stores the take-up force of the coil spring 103. When the external force is removed, the coil spring 103 is driven to rotate in the reverse direction under the tension of the coil spring 103, and the reel 102 winds the braid 104 on the reel 102 one circle by one circle, so that the purpose of winding the braid 104 is achieved. The automatic webbing retracting device 10 of the present invention can automatically retract the excess webbing 104 when the webbing 104 is not used or during use, so that the device is cleaner and more convenient, and also prevents the webbing 104 from being lost due to being abandoned after being detached. In some embodiments, the forward direction may be clockwise and the reverse direction may be counterclockwise, or vice versa.

As shown in fig. 12, a bedside bed 20 comprising the aforementioned automatic webbing retracting device 10 is disclosed. The bedside bed 20 includes a bottom panel 202 and a plurality of side panels 201. The bottom plate 202 is substantially parallel to the ground, the side plates 201 are substantially perpendicular to the ground and surround the bottom plate 202, and a webbing outlet 2011 is arranged on each side plate 201. The automatic webbing retractor device 10 is mounted inside the side plate 201, and the free end 1042 of the webbing 104 passes through the webbing exit 2011. In this embodiment, one automatic webbing retractor device 10 is provided on each of the two side plates 201. The automatic webbing retractor device 10 may be secured to the inside of the side plate 201 by connections common in the art, such as by screw connections or other means. Alternatively, the base of the automatic webbing retractor device 10 may be integrally formed with the side panel 201, as shown in fig. 5-7, 10 and 11. The automatic webbing retractor 10 also includes an engagement member 107 provided at a free end 1042 of the webbing 104. The catch 107 comprises a first catch 1071 and a second catch 1072 which by a snap action secure the free end of the webbing to a fixed point (not shown) near the bedside 20, for example a bed on which a caregiver sleeps.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention.
